One of the sh**test pre’s I’ve ever had, had me consistently yawning throughout my workouts and could not feel it kick in one bit. Barely any citrulline and beta-alanine and just trash. Now that I’ve moved into a different pre I can actually make it through my workouts without being put to sleep

I have tried several other pre-workouts and enjoyed them all, but this one is by far my favorite. I always buy some when it's on sale/has a promotion. Literally makes me feel like a God when I am lifting.
Only down side is the "Test Boost" side of it. I do notice a change in mood a bit while I use it, but nothing wild. Would definitely read up before using it alongside another test booster (Might just be a mental thing over an actual side effect, but still).
All in all, a must try for anyone. Even if it's not your all time favorite like it is mine, you will still love it.

I will give a 10/10 for the product. It is my third day and i will say it has worked wonders for me already. I am a cross fit athlete and powerlift heavy weights throughout the week. I can bench 100*2 kgs, deadlift 190*! kgs and squat 170*1 kgs before using this one. I have seen dramatic improvement in just 3 days and am able to bench 110*2 , deadlift 200*1 and squat 190*2 (in kgs) already.
Post my powerlifting session i still have enough stamina to keep going for my weight training.
Thumbs up to GAT nutrition!!

The pina colada flavor is second to none- easily the best tasting pre workoutI've ever had. A little high on the caffeine scale but if you have a high tolerance I definitely recommend Nitraflex. They make it with creatine now too!

Very smooth texture. Mixes well. It doesn’t have the super caffeine energy like other pre workouts. But a longer lasting good energy pump. I just eat the scoop because it takes about 45 mins to kick in when you mix it. Great product would def buy again

Nitra Flex is great gives you a good pump as well as motivation to get a great workout in! Definitely follow recommended amounts. Once I used it for about a month took a week off of it and went right back on it, during that week off of the product i felt alot more sluggish and exhausted during the work out which just made me enjoy it even more once i got back on it. I like the pina colada flavor definitely recommend it with cooler water and the watermelon is good with room temperature water as well as cold.

Just Awesome! Everything you could want to be included in a pre-workout. Vasodilation, test-boosting, caffeine in good amounts. Even with that all included, I didn't experience a thermogenic "shaking" that you get with other pre-workouts, which allowed me to focus on my lifts. Mixed well, servings are balanced, gave me an edge in the gym. If you want something to get over a plateau, I would definitely check NITRAFLEX out!

Mixability: didn't even use a shaker and it mixes pretty well.
Flavour: I really liked it but it is kinda sour, also it has somewhat of a fizz. No big deal anyways, was totally drinkable.
Effect: ****. I don't take pre often, just when i am about to face some intense training. I have tried many brands, but this is just a whole new deal.
You feel it instantly, gives a lot of energy and focus, and a little bit of an itch (i'm pretty sensitive so take this lightly). Would def buy again.

I have to disagree about this pre workout, I thought maybe I got a bad tub the first time but this pre workout just doesnt have enough of the few good ingredients it does have. Half a serving of citrulline and less than half a serving of beta alanine is pretty much all that's in this besides the 325 mg of caffiene. decent energy with this pre workout but not much else

Been using nitraflex for about a year now. I've tried black cherry, blue raz, watermelon, green apple and just tried orange. ALL the flavors are excellent. My only criticism in the flavor department is it needs a little more water than recommended. I use 12-13 ounces. As far as does it work...Yes, most days. Seems hit and miss for me but when it works, it works....The only thing preventing me from giving it an overall 10 is it (and others) isn't the best workout I've ever had. Nothing seems to give me that rush the original NO Xplode had. But I will say it is the best tasting PWO I've tried so far.
